设有3个值大小不同的整数a，b和c，试编写一个C++函数，比较三个数的大小

#include <stdio.h>

void compare(int &a,int &b,int &c)
{
int large,mid,small,t;
if(a<b)
{t=a;a=b;b=t;}
if(a<c)
{t=a;a=c;c=t;}
if(b<c)
{t=b;b=c;c=t;}
large=a;
mid=b;
small=c;
}

void main()
{
int a=12,b=34,c=3;
compare(a,b,c);
}

#include <iostream>
using namespace std;

void compare(int &a, int &b, int &c)
{
int t;
if(a < b)
{
t = a; a = b; b = t;
}

if(a < c )
{
t= a; a = c; c = t;
}

if( b < c)
{
t = b; b = c; c = t;
}

cout << "值最大的整数: " << a << endl;
cout << "位于中间值的整数: " << b << endl;
cout << "值最小的整数: " << c << endl;
}

int main()
{
int a, b, c;

cout << "输入三个数字,中间用空格隔
